الوصف: Recent results on the detection and genetic characterization of stool-associated RNA viruses from different species have increased the knowledge about the extreme genetic diversity of picornaviruses. This study aimed to investigate the presence of unclassified porcine stool-associated RNA viruses (posaviruses) in South Korea and to elucidate the molecular evolution of the viruses. By RT-PCR, posaviruses 1 and 3 were exclusively found in fecal samples and consistently detected in three consecutive years in six of eight provinces, with 148/697 (21.2%) and 33/84 (39.3%) positive samples and farms, respectively. Every age group but the older age groups (finisher, sow) had significantly higher positive rates of posavirus 1 than posavirus 3. An analysis of the RNA-dependent RNA polymerase sequences by likelihood mapping and maximum-likelihood-based phylogenetic analysis revealed that stool-associated RNA viruses formed four supergroups that were well separated from all recognized families of the order Picornavirales. Five genomes of Korean posaviruses generated in this study were phylogenetically grouped with posavirus 1 and posavirus 3 and were predicted to have the typical genome organization of picornaviruses.
